When replacing your factory radio with an after-market car stereo, the Scosche GM02B wire harness is a must for a quick and clean installation. It eliminates cutting your OE radio plug. After connecting it, your install is simple as the wires will color-match and easily connect to the after-market stereo. Without the Scosche GM02B, you would have to cut the OE radio plug and manually test each wire to connect to your after-market receiver.

In addition, because you do not have to cut your OE radio plug off, the GM02B allows you to reinstall your factory receiver if necessary. A great example is if you sold your car, but wanted to keep your after-market radio and re-install your factory stereo receiver. We also recommend the Scosche BOBAZT for a quick connection that is sure to last.

I chose this because I know when I new head unit gets in, the plugs in the back will need to be soddered with these wires to make an easy connection from the car's original factory wires running for/from the old one to the new one.

I have a 2000 toyota camry v6. It has 6 speakers (2 tweeters, 2 front, 2 rear) but this harness seems to have connections for only 4 speakers as stated in the description. Will this mean my twwters will be silent?

Best Answer:Correct. The harness has connections to 4 speakers; the tweeters are actually connected to the front door speakers, so there is no need for extra two cables, I changed both front speakers and tweeters, no need to worry, just splice the new tweeters into the existing cables

You will need a crossover to wire the tweeters. That is if the tweeters are mounted separately from the front or rear speakers. If they are built into the speaker, they already have crossover built in and you only have to wire the speakers.

Will this work on a 2002 sr5 4runner? Don't want to buy without being 100% sure.

Best Answer:I put mine in a 2001 Tundra. While I initially panicked because the colors of the wires coming out of the truck did not match the wiring harness, I found a chart of Toyota wiring online which shows that it will work fine. Once I got all the wires crimped together, it just snapped into place and works great.

Assuming the NON-AMPLIFIED System, Yes. If your vehicle has the amplified system, then you seek the Metra 70-8113. (Please check the back of your Aftermarket Headunit. If it DOES NOT have FOUR RCA Preouts, then instead pick up the Scosche TA03B) .
